The Super Bowl caused Netflix viewing to drop by 30%

"Super Bowl 53, which saw the New England Patriots defeat the LA Rams in a poorly received contest, had a profound effect on Netflix usage on Sunday evening – with data surprisingly being released by Netflix themselves.
During the game, Netflix posted on its Twitter account: “So apparently this Super Bowl thing is kind of a big deal … looks like Netflix viewing in the US is down about 32% compared to a normal Sunday.”"
